Subject [jira] Created: (HADOOP-5435) JT should remember blacklisted TT after restart
Date Sat, 07 Mar 2009 07:30:56 GMT
JT should remember blacklisted TT after restart
-----------------------------------------------

                 Key: HADOOP-5435
                 URL: https://issues.apache.org/jira/browse/HADOOP-5435
             Project: Hadoop Core
          Issue Type: New Feature
          Components: mapred
    Affects Versions: 0.20.0
            Reporter: Ramya R


Currently, when JT is restarted , it does not remember any TT(s) which was blacklisted across
the cluster before the restart. It would be useful if a new feature could be added for JT
to remember blacklisted TT(s) even after restart. This would avoid JT from assigning tasks
to faulty TT(s) each time after restart.
